摘要: The present invention relates to a process and plant for removing acid gases such as carbon dioxide, sulphur containing compounds and nitrogen containing compounds from gas streams including high and low pressure gas streams. A solvent solution containing alkali carbonates absorbs the acid gases including carbon dioxide and either one or both of sulphur and/or nitrogen containing compounds. The bicarbonate is regenerated into a carbonate form to provide a gas stream rich in carbon dioxide, and sulphur and/or nitrogen containing compounds are recovered.

摘要: The present invention relates to gas separation membranes for separating carbon dioxide from other gas species, polymer compositions suitable for this application, and processes for the manufacture thereof. In particular, the present invention relates polymeric compositions comprising a host polymer that is permeable to the targeted gas species, such as carbon dioxide and has a selectivity for the target gas species over other gas species. The polymeric composition also comprises domains of a polymeric material that are, for example at least 0.5 nm in diameter and that have a higher permeability for the targeted gas compared to the host polymer. The present invention can provide membranes that have a permeability and selectivity above the Robeson's upper bound.
